I'm not sure I understand. How can I use that variable and be assured
that (assuming you mean "sId" parameter) it writes back to the correct
DIV?
For example, on one particular page I call that function 3 times in
sequence:
updateCount('div_one');
updateCount('div_two');
updateCount('div_three');
Each time the function is called it's with a different ID, so when
"onComplete" fires, I need to know which particular ID is going to be
written to so that I can write "n/a" in the event that a numeric
string was not returned. If the 2nd call fails, for example, then how
do I know to write "n/a" to "div_two" and not "div_three"? I hope that
makes sense.
